Hi, I had ivf done and transferred 3 embryos, I'm now 5 weeks a few days pregnant hcg level was 2302, heavy bleeding occurred, went to Er, u/s shows 1 yolk sac, cervix is closed, but hcg level dropped to 2200. Is it possible that being that 1 yolk sac could mean the bleeding was the other 2 embryos that didnt implant? Or. This an indication that I will miscarry?
